Introducing the 'World's Cutest Sea Monster': Scientists Uncover an Adorable Snailfish Nearly...

A New Species Discovered in the Depths of the Ocean

When exploring the deepest parts of the ocean, one would expect to encounter something that is both intimidating and alien. However, scientists were surprised when they stumbled upon an adorable new species of snailfish, thriving under extreme conditions.

This remarkable discovery was first made in 2019 by a team of researchers who were investigating the seafloor off the coast of California. Using a remotely operated vehicle, they descended to a depth of 3,268 meters (10,722 feet). There, they encountered an adult female snailfish measuring 9.2 centimeters (3.6 inches) long, swimming calmly amidst the crushing pressure, frigid cold, and eternal darkness.

Recent analysis has confirmed that this creature belongs to a previously unknown species, which has been named the bumpy snailfish (Careproctus colliculi). The snailfish family is known for its large head, jelly-like body covered in loose skin, and narrow tail. Many species also have a disk on their belly that helps them grip the seafloor or hitch a ride on larger animals.

Fans of the snailfish have described it as "adorable" and "the cutest sea monster" they have ever seen. One person even likened it to a "real life Pokémon" after watching a YouTube video of the new species. Mackenzie Gerringer, associate professor at the State University of New York at Geneseo, emphasized the beauty and diversity of life in the deep sea. She said, “Our discovery is a reminder of how much we have yet to learn about life on Earth and of the power of curiosity and exploration.”

The discovery was made by a team from the Monterey Bay Aquarium Research Institute (MBARI) during an expedition to the outer reaches of Monterey Canyon, approximately 100 kilometers (62 miles) offshore of Central California. While collecting this individual, the researchers noticed unique features that set it apart from other deep-sea snailfishes they had encountered before.

To confirm their findings, scientists used microscopes, micro-CT scans, and careful measurements. They also analyzed two other specimens and found that these were also new to science—named the dark snailfish and the sleek snailfish.

The bumpy snailfish has a distinctive pink color, a round head with large eyes, wide pectoral fins with long uppermost rays, and a bumpy texture. The dark snailfish, on the other hand, has a fully black body with a rounded head and horizontal mouth. The sleek snailfish stands out due to its long, black, laterally compressed body, absence of a suction disk, and prominently angled jaw.

This encounter is the only confirmed observation of the bumpy snailfish, so further details about their full geographic distribution and depth range remain unknown. Steven Haddock, senior scientist at MBARI, led the research expedition that first encountered the bumpy snailfish. He emphasized the importance of documenting deep-sea biodiversity, stating that it is "critical to detecting any changes that may be occurring in this environment."

Scientists have described more than 400 different species of snailfish worldwide. These fish inhabit a variety of ocean habitats, ranging from shallow tide pools to deep-sea trenches. In fact, a snailfish holds the record for being the deepest-dwelling fish.

The new species was described in the journal Ichthyology and Herpetology.

What Is a Snailfish?

Snailfishes belong to the family Liparidae. They typically have a large head, a jelly-like body covered in loose skin, and a narrow tail. Many species have a disk on their belly that allows them to grip the seafloor or hitchhike on larger animals, such as deep-sea crabs.

Shallow-water snailfishes often cling to rocks and seaweed, curling up like a snail. Scientists have described more than 400 different species of snailfish worldwide. These fishes make their homes in a variety of ocean habitats, from shallow tide pools to deep-sea trenches.

In fact, a snailfish holds the record for the deepest-dwelling fish. How do deep-sea fish like the mysterious snailfish endure pressure 1,000 times greater than sea level? What stunning discoveries have scientists made in the deep sea? From colossal squids to monstrous creatures, the ocean continues to surprise us with its hidden wonders.
